Use the equations of motion (where helpful) to solve the following problems.
1. Consider a sports car, capable of accelerating from rest at 5 m/s/s. If it accelerates uniformly for 8 seconds, find:
a. the velocity after 8 seconds
b. how far the car has gone in this time
Now assume that the driver applies the brakes and the car uniformly comes to a halt in 3 seconds.
c. What is the acceleration during this braking time?
d. How far does the car go during this time?
Draw two graphs that represent:
a. the displacement vs. time for the entire trip
b. the velocity vs. time for the entire trip
2. Imagine that a falling body accelerates at 10 m/s/s. It is released from a high tower:
a. If it takes 3.5 seconds to hit the ground, how fast is it traveling immediately before hitting the ground?
b. If it took 3.5 seconds to hit the ground, how tall was the tower from which it was released?
Keep working on your lab report. Expect a draft to be due by Friday.
